Abstract
A flat reducing and sawing installation for processing tapering logs includes a reducing section and a sawing section through which logs pass in sequence. The reducing section includes two reducing disks which can each be moved outwards by respective positioning devices. The sawing section includes at least two laterally movable saw blades. The position of the reducing disks is controlled by an electronic evaluation and control unit on the basis of profile data fed in about the log, which indicates that at least one of the disks is about to grind sufficient material from one side of the log to form a plank of a minimum acceptable thickness, length and width. Under these circumstances, the control unit moves the appropriate reducing disk outwardly by at least the minimum acceptable thickness to allow the outermost saw of the sawing section to saw off the resulting plank.
